The concept of magic square is that magic square is a mathematical concept, which is a square matrix composed of numbers, in which each number only appears once, and the sum of numbers on each row, column and diagonal is the same.
Magic Square is a method of arranging numbers in a square grid so that the sum of numbers in each row, column and diagonal is equal. Rubik's Cube is also a traditional game in China. In the past, this was more common in government and schools. It arranges one to several natural numbers into a square with several numbers in vertical and horizontal directions, so that the sum of several numbers in the same row, column and diagonal line is equal.
The number of Rubik's cubes has not been solved. Definition of anti-magic square: In a square composed of several numbers arranged neatly, the sum of several numbers on any horizontal line, vertical line and diagonal line is not equal, and a chart with this property is called anti-magic square.
The biggest difference between the anti-Rubik's cube and the positive Rubik's cube is magic and difference. All the magic sums of the positive magic square are the same, while all the magic sums of the negative magic square are different. The so-called magic sum is the sum of several numbers on any row, column and diagonal of the magic square.
The earliest Rubik's Cube in Europe was painted by the famous German painter albrecht Toure, with a fourth-order Rubik's Cube on it, and the two numbers behind the Rubik's Cube happened to be the year when the painting was made (15 14), which is the oldest Rubik's Cube in Europe.

China Rubik's Cube Association's top ten masters: Guo Xianqiang, Pan, Su, Wu Shuoxin, Niu, Peng and Zeng are all grassroots Rubik's Cube experts in China, who have made a series of important achievements in Rubik's Cube academic research, many of which are ahead of their international counterparts.
, Li, Guo Dayan, and other Rubik's Cube predecessors have also made selfless contributions to the research and development of China Rubik's Cube, and many of them may have forgotten their names. Perhaps their past research results seem unremarkable today, but their historical stage has provided positive nutrients for the research of our latecomers.
